Charlie Morton, last 3 starts

Charlie Morton, regular season

Morton is winless in his past five starts. Solving his first-inning troubles would help snap that streak: In his 12 starts, he has allowed 16 runs (15 earned) in the first. He is undefeated in past six GABP starts (3-0, 2.70 ERA).

Keyvius Sampson, last 3 starts

Keyvius Sampson, regular season

Sampson will make his first career start after making his Major League debut on Thursday with one scoreless inning of relief work. He gave up only five hits across eight scoreless frames in his last start with Triple-A Louisville on July 24.

John Lackey, last 3 starts

John Lackey, regular season

John Lackey looks for his 10th consecutive quality start when he faces a Reds team that he dominated his last outing. The veteran righty allowed just two hits in eight innings against Cincinnati on July 29, but picked up the loss in a 1-0 decision.

Anthony DeSclafani, last 3 starts

Anthony DeSclafani, regular season

DeSclafani had one of the best starts of his career his last time out against the Cardinals on Wednesday. He gave up just three hits across seven scoreless innings to pick up the victory. It was only his second career appearance against the Cards.

Carlos Martinez, last 3 starts

Carlos Martinez, regular season

Martinez unraveled a bit against the Rockies on July 30 after rattling off a streak of 11 straight quality starts, but the All-Star is still in the midst of a stellar campaign that has seen the Cardinals go 16-5 in games he pitches.

David Holmberg, last 3 starts

David Holmberg, regular season

Holmberg picked up the victory in his 2015 season debut against the Pirates on Thursday. Dating back to last year, he is 3-1 with a 2.05 ERA in his last six appearances, including four starts. However, his lone loss came to the Cardinals on Sept. 19.

Michael Wacha, last 3 starts

Michael Wacha, regular season

Wacha got back on track in his last start by throwing seven scoreless innings vs. the Rockies. He will try and parlay that into success against the Reds, who he subdued in his first two starts of the year on April 11 and 17.

Michael Lorenzen, last 3 starts

Michael Lorenzen, regular season

Lorenzen has to be happy to flip the calendar to August after a terrible stretch in July. The rookie righty went 0-4 with an 8.61 ERA in five starts during July. He went six innings just once during that stretch.
